  11   13       Pwrite(struct ps_prochandle *P, const void *buf, size_t nbyte,

  14   16  DESCRIPTION
  15   17       The Pwrite() function writes data from buf to the process handle P
  16   18       starting at the address address.  It writes at most nbyte of data.  The
  17   19       Pwrite() function is logically analogous to the pwrite(2) function.

  18   20  
  19   21       For live processes, this function is equivalent to writing to the /proc
  20   22       file system as file for the process.  For core files, it writes to the
  21   23       logical address space of what was once the process and not the
  22   24       corresponding offset in the on-disk file.  ELF objects grabbed through
  23   25       Pgrab_file(3PROC) do not support being written to.
  24   26  
  25   27       The Pwrite() function cannot be used to extend the size of a mapping;
  26   28       writing to an unmapped region generates an error.
  27   29  
  28   30  RETURN VALUES
  29   31       Upon successful completion, the Pwrite() function returns the number of
  30   32       bytes successfully written to P.  This number is never greater than
  31   33       nbyte.  Otherwise, it returns -1 and errno is set to indicate an error.
  32   34       For the full list of errors see the DIAGNOSTICS section in proc(4) and
  33   35       the ERRORS section in pwrite(2).
  34   36  
  35   37       In addition, the Pwrite() function will fail if:
  36   38  
  37   39       EIO                P refers to an ELF object and not a core file or
  38   40                          active process.
